To all lwhom 'it may concern:

' Be it known that I, ERNST IRoonasna, a citizen of the United States ofAmerica, re siding at Alton, in the county of Madison have 'Inventedcertain new and useful Improvements in .Coal or `Ore `Washers, of .whichthe following is a full, clear,'and exact descri tion, reference beinghad to lthe acgompaxg'ing drawings, form part of 'this specification.

My invention relntegfto, means for controlling the discharge ofsate,ore, or other .relatively heavy matters from ^the washing tanks of coalor ore washers after they have washing tanks from been deposited in saidthe object of the 1nthe jig-s of the washers,

` vention being to provide means whereby sax heavy matters may bedischarged separately from each of abattery or series of washersassembled. with each other, and operable in a manner to provide for eachoutlet being continually in a closed condition.

A. further object 'oiv the invention is to provide for the separatedischarge of heavy matters from the several washing tanks independent'ofeach other, with the object in View of permitting examination of theheavy matters delivered from each tank without mixture of the mattersdischarged from the several tanks.

Figure l. is a vertical cross section through a washer equipped with mydevice. Fig. 'lll' is a front elevation o'f the end washer of a batteryof Washers. Fig. III. is in part an enlarged vertical section of thelower por-l tion of a washer and in part an elevation ofp my device.Fig.' 1V. is a longitudinal section through the gate of my device, itsshaft, and an operating means upon said shat't. Fig. V is a frontelevation of my device showing a battery of washers.

In the 'accompanying drawings :-1 designates the jig ot' the washerhaving an iml purities outlet 2 that is controlled by a gate'.

The jig is supported and reciprocated vertically in any usual manner,such as by the employment of hangers a that are actu ated by eccentrics5 upon eccentric shafts 6.

.'lhe jig operating means and the means for controlling the impuritiesoutlet 3' of the jig ma be that-illustrated in the drawings, for

which no invention is herein claimed, or any'I other suitable mechanism.y

if designates the washing tank of the washer inV which the jig 1operates and which is provided with a converging hopper Y 19 is a pawlloosely fitted bottom 8. At the bott-0m of the washing tank is an outlet9.

10 designates a gate housing of a dischargel valve suitably supported atthe bottom ofthe washing tank and which'has an inlet in communicationwith the outlet 9 of vsaid tank, (as seen in Fig. I.) andis providedwith an escape opening 11 at the bottom. 12 is a chute located beneaththe escape opening of the gate housing and into which the material thatpasses through said gate housing may descend to be delivered into aconveyor 13 that may be of any preferred construction.

The body of the gate housing 10 is of approximately cylindrical shape incross scction and within said gate housingis-a closely fittingchamber-ed controller or segmental gatel/l, (see Figs. I and IV,)that-is adapted .to be rotated in the gate housing by means to be nextdescribed. -15 is a gate shaft that extends longitudinally in the gateIhousing and to which the heads ofthe segmental gate 14 are fixed. Thisshaft is hori- .zontally arranged and has txed lto it, ex-

telriorly of the gate housing, a ratchet wheel 16. 17 are rocker arms'the shaft 15 on opposite sides of'and adjacent to the ratchet wheelthereon and in the outerends of which is mounted a rod 18. to the rod 18and adapted to engage the teeth-ot theratchet wheel 16, (as seen in Fig.III.) 20 is a 'reciprocating operating rod having afork 21 at i'ts.inner end that embraces the pawl 19 and is ivoted to the rod 18 of therocker arms 17, and through the medium of which said rocker arms aremoved backwardly and forwardly to cause the pawl lt) to impart rotationto the ratchet wheel 16, the shaft 15 on which mounted, and thesegmental gate 14. 'l at its outer end to an eccentric strap 22 thatsurrounds an eccentric 23' upon a. driven shaft 24.

It will be seen that upon rotation of the shaft 24 and the eccentrlcthereon, reciprocatory movement is imparted to the o eratling rod 20,and as a consequence o said movement of the operatin rod, the rockerarms 17. are moved to an fro to perform theiinoffice The driven shaft 2ahy which the eccentric 23 is carried is operated by connection tome ofthe jig operating eccentric shafts 6, the means ein loyed for thisconnection being`preterab y a sprocket chain loosely itted to operatingrod 2Q is connected 25 that operates upon a lower sprocket wheel manner'with the result 26 on the shaft 24, and an' upper sprocket wheel 27upon a jig operating'eccentrlc shaft.

In the practical use of a Washer having my improvement incorporatedthere1n, the jig of the washer is operatedin theusual of causing theheavy matters that are discharged Afrom the jig 'to escape therefrom andto descend into the washing tank. These heavyr matters fall 1n thewashing tank to the outlet 9 .infwhichv gedby opening they accumulate tobe dischar f the segmental. gate 14. During the operagate is tionwiththe inlet at such .outlet mayenter through said inlet.

This shield is adapt-- ed to bemoved toward the point of. the pawl 19 by suitable means, such as anarm' 30, I fixed to the shield and it an'. operating rod 31.
